Check Digit Verification of cas no

The CAS Registry Mumber 648417-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,8,4,1 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 648417-71:
(8*6)+(7*4)+(6*8)+(5*4)+(4*1)+(3*7)+(2*7)+(1*1)=184
184 % 10 = 4
So 648417-71-4 is a valid CAS Registry Number.

Synthesis and binding study of phosphonate analogues of PNAs and their hybrids with PNAs

Efimov, Vladimir A.,Choob, Michael V.,Buryakova, Alla A.,Chakhmakhcheva, Oksana G.

, p. 1671 - 1679 (2007/10/03)

The preparation of monomers for the synthesis of phosphonate analogues of peptide nucleic acids containing the four natural nucleobases: thymine, cytosine, adenine and guanine, has been accomplished. The monomers obtained were used for the automated online solid phase synthesis of pure phosphono- PNA oligomers as well as chimeras consisting of phosphono-PNA and PNA resudies. The hybridization properties of these oligonucleotide mimics to complementary DNA and RNA fragments were studied.
